It’s great to see Google developing some great apps for the Mac. In an effort to show that its employees’ “20 percent time” is benefiting Mac users, Google unveiled its officially unofficial sandbox for Mac developers today.

Google can now tap into information broadcast from mobile towers to approximate your devices current location on the map. “It’s not GPS, but it comes pretty close..” Google explains on its website. I’ve installed this and tried it in New York. It’s amazingly accurate, and on my N95 you can activate true GPS too. Very cool.
